IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Letters Patent No. 174,335, dated February29, 1876; application filed January 29, 1876.

To all whom it may concern:

Be it known that I,J1vo. S. WILLIAMSON, of Ringoes, in the county ofHunterdon and State of New Jersey, have invented certain new and usefulImprovements in Insect- Screens for Windows; and I do hereby declare thefollowing to be a full, clear. and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the; accompanying drawings,which form part of this specification, in which- Figure 1 is aperspective, and Fig. 2 is a broken vertical longitudinal section, of myinvention. 7

The object of my invention is to provide an insect-screen which can bereadily applied to any Window without the employment of ribs or strips,which can be inserted and withdrawn at any position, which can beadjusted at any altitude, and which will not injure or deface the frameto which it is applied.

My invention, accordingly, consists ofarect angular frame or sash,having its central opening covered with netting, either fibrous ormetallic. The sides of this frame are plowed or grooved for the passageof studs or screws secured to the window-frame, the edges being alsoprovided with material of a soft or yielding nature, so as to preventinjury to said window-frame. A look or bolt of suitable construction isalso provided to enable the screen to be retained at any height to whichit may be adjusted.

Referring to the accompanying drawing, A represents a window-frame,having an upper sash, B, and lower sash G, of the usual or any suitableconstruction. D D are studs or screws, inserted at suitable distancesalong both sides of the frame A, as shown. E represents a rectangularframe, upon which is stretched gauze or netting-F. The sides of saidframe are plowed or grooved, as shown at e, for the passage of the studsor screws D. Said sides are also cut away or slotted, as shown at c, forthey lateral passage of said screws or studs in inserting or withdrawingthe screen from the window. G is a bolt, by means of which the screenmay be adjusted to cover the opening left in the window by drawing downthe upper sash. H shows a strip of rubber, cloth, or other softmaterial, folded so as to puff, and tacked or otherwise attached to theedge of the frame E. The

object of this material is to fill'up completely the space between theedges of the frame E and adjacent sides of the frame A, it beingnecessary to leave some space in order that the screen will move readilyand easily. This material permits such easy movement, at the same time,preventing any rubbing which would injure the window-frame, and avoidingleaving any crack or crevice.

-The advantages of this screen are as follows:' First, it is cheaply andeasily 'con-' structed, and may be readily applied to any window withoutremoving either of the sashes. Secondly, it requires the provision of noribs or strips-about a dozen ornamental screws, which may be insertedinthe window-frame without defacement of or injury to the latter, beingall that is required for its attachment to a window. Thirdly, it willserve to close the opening left by raising thelower windowsash or theopening left by depressing the upper sash alternately, thus serving asan adjustable screen for day and night, the lower window-sash beingraised during the day, and the upper one lowered by night. Fourth, itcan be inserted or withdrawn at any altitude, and is a completeprotection against the entrance of insects.

What I claim as my invention is 1. The frame E, having its sides plowedor grooved at c, and provided with gauze or netting F, in combinationwith the studs or screws D, inserted in the frame A, substantially asshown and described.

2. The frame E, having grooves e and slots 6, for the lateral passage ofthe studs D, substantially as shown and described.

3. In combination with the window-frame A and sliding frame E, the studsor screws D, arranged in vertical lines for the retention and sliding ofsaid frame E, substantially as shown and described.

4. In combination with a window-frame, A, and sliding screen-frame E,the folded rubber or cloth guard-strip H, attached to the sides of thelatter, substantially as and for the purpose set forth.

- 1n testimony that I claim the foregoing I have hereunto set my handthis 18th day of January, i876.
